I recently set one up for fpv:
Fpv hobby 5.8gHz tx
FirstPersonView 540tvl 2g cam
Wired to a separate 1s 160mah Turnigy

The gear weighs about 11g including battery and wiring, which is less than a key chain cam. Get about 7mins flight time with a 1s hyperion 550mah. Lots of fun and really simple to setup and fly, although wind is an issue.

Next up is a home made cloverleaf for the tx and possibly a microphone.

Can you give me a link to everything you have there so i can buy exactly the same as you have. What is the range?
And i don't know if you use googles, but i want to can you find someone that works with the oter stuff?

this is basically the same setup I've been using on my mQX, with one major difference. The lens he has on this setup shown above is way too narrow at 55 degrees for my tastes. I'm using a 90 degree lens and it gives a much better perception of flight. I was unable to fly comfortably with the 55 degree lens. Here are a few sources to check out for this kind of gear. Keep in mind there are several bands available for the skyRF/boscam boards that most of these micro setups use. You have to be careful you source a vtx that matches your vrx, for instance most of these micro 5.8GHz vtxs won't work with the fatshark/airwave frequency sets. Also, a little tidbit for indoor flying on 5.8GHz... 200mw is enough to create significant multipathing problems, even with CP antennas. If you want to fly indoor you might want to look at the 10mw vtx module with CP antennas on both vtx and vrx. http://www.foxtechfpv.com/58g-tx5813...fly-p-271.html

funny, I just recently made a simple mQX FPV build log recently. all the parts I have used including links to where you can get them are in the video description and also mentioned in the video itself. have a look:
